WILLIAM B. MPHERSON AND WESLEY CAHOON, OF DEADYVOOD, (DAKOTA TERRITORY.) SOUTH DAKOTA.

HYDRAULIC lMOTOR.

SPECIFICATION forming part of Letters Patent No. 421,605, dated February 18, 18.90.

Application filed July 26, 1889. Serial No. 318,708. (No model.)

To all whom, it may concern: I Beit known that we, VILLIAM B. MC- PHERsoN and WESLEY CAHooN, citizens of vthe United States, residing at Deadwood, in

pressure upon the shaft or aXisof the wheel, which is an objectionable feature in many of this class of machines as vordinarily conwith the operation of the bucket-wheel. The The invention consists in the improved structed.

construction of the bucket-wheel and its casing, which latter forms a receptacle or reservoir for the water; in the combination, with the said bucket-wheel and casing, of deflecting-plates to prevent the water discharged from the wheel from reacting against the latter; and in the improved construction and arrangement of details, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a perspective view of our improved hydraulic motor, parts of the casing of the same having been broken away for the purpose of showing the construction more clearly. Fig. 2 is a vertical longitudinal sectional view taken' at right angles to the shaft or axis. Fig. 3 is a vertical transverse sectional View taken on the linen: in Fig. 2. Fig. 4 is a front elevation of the bucket-wheel.

Like numerals of reference indicate like parts in allthe figures.

A suitably-constructed frame 1 is provided with bearings or boxes 2, in which is journaled the shaft 3, carrying the bucket-Wheel 4 of my improved hydraulic motor. Said bucketwheel consists of a central hub or disk 5, having radially-extending plates or buckets (i 6, located equidistantly around its periphery. Said buckets consist of plates of metal or other suitable material, the upper sides of Which are provided with central longitudinal ridges 7, adjacent to which are formed-channels or eorrugations 8 8, one on each side. The outer corners of the said plates or buckets are V`curved upwardly, as shown at 9 9, lthus imparting to the channels 55 8 S the form and character of scoops andv a tendency to discharge the water at the sides of the plates or buckets, the object of which will be perfectly understood when the nature of the water-casing and the method of dis- 6o charging the water upon the bucket wheel, which will be hereinafter described, are taken into consideration.

The bucket-wheel is surrounded by an annular casing 10, the inner wall ofwhich 11 is 65 as nearly in contact with the outer edges of the buckets as it may be Without interfering upper en d of said easing is provided with an inlet 12, which is connected with the water- L7o supply, and the said casing has a series of interiorly-arranged chutes 13 13, arranged in the direction of rotation of the wheel and having openings 14, which face the uppersides of the radial plates or buckets.

Bolted or otherwise suitably secured to the outer walls of the annular casing 10 are the shells or guards 15, the outer ends of which are provided wit-h openings 16 for the passage of the ends of the shaft. Tubular casings 17 8o for the said shaft are secured to the inner sides of the guard-plates 15, and the inner ends of said tubularcasings are provided with circular disks 18, of a diameter about equal to that of the hub of the bucket-wheel, with Y which the said plates are nearly in contact. The tubular casings 17 and disks 18 are for the purpose of preventing the water discharged from the bucket-wheel from escapingthrough the sides of the shells or guards 9o around the projecting ends of the shaft. The shells or guards have downwardly-extending escape-passages 19, which are connected by means of a suitably-constructed funnel l2O, through which the water is eventually discharged.

Suitably mounted upon the tubular casings 17, which surround the shaft, are a pair of deflectingplates 21, one of which isv arranged on each side of the wheel, and the upper ends of Ico which have concave inner sides, said`Y upper ends being also curved in an inward direction.

These plates are for the purpose of preventing the Water discharged at the side of the Wheel from reacting against the latter and thereby impeding its operation.

The annular casing l0 of our improved hydraulic motor is provided with laterally-extendinglugs 22, adapted to rest upon the upper edge of the frame l.

The boxes or bearings 2 of the shaft are provided with oil-cups or lubricators of suitable construction, through Which the said bearings may be automatically supplied with lubricat ing material. The projecting ends of the shaft are provided with collars 23, to retain said shaft in position in its bearings Without any tendency to lateral movement, whereby the hub of thebucket-Wheel might be carried into frictional contact with either of the disks 18 and one of the projecting endsof Vsaid sliaft is provided with aband Wheel or pulley 24C, from which motion maybe transmitted, by means of a belt or band, to the machinery i'vhieh iste be driven. d

The operation and advantages of our improv dliydraulic motor will be readily understood frointhe foregoing description, taken in connection with the drawings hereto annexed, by those skilled inthe artto which" it appertains. VIt willbe s een that the Water enteringthe annular lcasing completely .iills the latter and is discharged through the openings 14 Aof e the chutes 13 around the entire rim or `periphery of the Wheel. The Water being discharged with` great ,force and at riglitangles to the buckets will cause the xfvheel to be rotated with great rapidity and power. Owing to the fact that both sides of the buckets are open for the discharge of ivater, and also to the improved construction of the, buckets, as herein described, therivater will be discharged equally on both sides and Without any tendency to lateral strain or pressure upon the shaft, which is apt `to occur in Water-Wheels of this character AWhere the discharge of Water is onone side'only.

v The general construction of our improved vaterfwlieel is simple and inexpensive, and it is practical and efficient in operation.

Having thus described our invention,\vl1at we claim, and desire to secure by Letters Patent, is-

l. In a hydraulic motor, the combination of an annular casing having interiorly-arranged chutes and slots or discharge-openings, a bucket-Wheel arranged Within the said casing, the shells or guard-plates, the tubular casings secured tothe latter surrounding the shaft of the bucket-Wheel and having disks at their inner ends, and the concave deflecting-plates mounted upon the said tubular casings adjacent to the sides of the bucket- Wheel, substantially as and for the purpose set forth.

2. The combination of the fra1ne,the, sliaft j ournaled in the sameand carrying thebucket Wheel, the annular casing or Watenelianiber having laterallyextending lugs supported upon the fraine, said Water-cha1nber being provided with intei'iorly-arran ged chutes and slots or discharge openings, the shells or guard-plates, the tubular casiiigs secured to the latter and surrounding the shaft ofthe bucket-Wheel, the defleeting-plates` `mounted upon said tubular rcasings, and the funnel connecting the lower `ends ofthe shells or guard-plates, substantially as set forthl,I j j In a hydrauliclnotor, the `cjoilbination, with a bucketfivheel having radiating `plates or buckets provided ivith longitudinal ridges, longitudinal grooves adjacent to saidridges, and upturned outer corners, of `an annular casing or Water-chamber surrounding `said bucket-,Wheel and 4having interiorly-arranged chutes and slots or `dischargefopenings, and defleeting-plates arranged adjacent to the sidesof the bucket-wheel to preveiitwwater discharged from saidivheel from reacting against the latter, substantially as set forth.
